 ## Create the LPG Dockerfile image
 
-Follow the instructions [here]( https://github.com/AI-Hypercomputer/inference-benchmark/blob/1c92df607751a7ddb04e2152ed7f6aaf85bd9ca7/README.md) to create the LPG image.
+Follow the instructions [here]( https://github.com/AI-Hypercomputer/inference-benchmark/blob/1c92df607751a7ddb04e2152ed7f6aaf85bd9ca7/README.md) to create the LPG image. Specifically, once you are in the inference-benchmark directory follow the steps below: 
+
+ * Create a repository in artifact registry to push the image there and use it on your cluster.
+
+```
+gcloud artifacts repositories create ai-benchmark --location=us-central1 --repository-format=docker
+```
+
+*  For Inifinity-Instruct and billsum datasets run
+
+```
+pip install datasets transformers numpy pandas tqdm matplotlib
+python datasets/import_dataset.py --hf_token YOUR_TOKEN
+```
+
+* Build a container to run the benchmark directly on a Kubernetes cluster
+using the specified Dockerfile.
+
+```
+docker build -t inference-benchmark .
+```
+
+* Push the image to the repository.
+
+```
+docker tag inference-benchmark us-central1-docker.pkg.dev/{project-name}/ai-benchmark/inference-benchmark
+docker push us-central1-docker.pkg.dev/{project-name}/ai-benchmark/inference-benchmark
+```
